Prince Caspian, the long awaited second installment of the C.S. Lewis classic Narnia series, opens this weekend.

In the Prince Caspian story, the Pevensie children return to Narnia, but 1,300 years have passed. Aslan, the Christ figure in the form of a lion, disappeared long ago. And with his departure, the faith and enchantment of Narnia disappeared as well.

In this film, Prince Caspian and the children are on a quest to bring Aslan back and once again, defeat the dark forces of evil.

C. S. Lewis' stepson, Doug Gresham serves as a co-producer on the movie. This has been a 20 year trek for Gresham, with the success of the first film.

"I always knew that if we made good movies out of the Narnian Chronicles-they'd be successful movies. If we stay as close as possible to the book, we'd have successful films," says Gresham. Series new comer, Ben Barnes plays the movie's title role.

"I think that the main sort of pressure came from myself in terms of wanting to keep it a faithful adaptation to what C. S. Lewis had written. I didn't want to make him some cool, swash buckling action hero because that's not really who he is in the books. He's very anxious about being, growing up, and becoming a man, a king, and a leader. And he doesn't feel very comfortable or like he deserves it. So I wanted to make sure that came across," says Ben.

William Moseley and Georgie Henley return in their roles as Peter and Lucy. Georgie shares how her character developed from the first film to the sequel.

"I definitely think that she's matured and gotten stronger. I think that also reflects me as well," says Georgie.

William adds, "I was training and training everyday with a stunt coordinator. On top of that, I was running as much as I could and doing a lot of horse riding because I wanted to commit to this aspect of the film, as to the best of my abilities."

Skandar Keynes returns as Edmund. And Anna Popplewell, once again plays Susan, the cautious and practical older sister.

Like The Lion, the Witch and the Wardrobe, this film serves up a powerful spiritual message.
